Description

Opening and closing device of sample storage container {APPARATUS FOR OPENING AND CLOSING SAMPLE STORAGE CONTAINER}

An object of the present invention is to provide an opening/closing device for a sample storage container capable of automatically opening or closing the lid of a container storing a drug or a sample to be used for a test.

Conventionally, drugs or samples to be used for testing are sealed in a small cylindrical container called a tube, and stored or transported by placing a plurality of these tubes vertically and/or horizontally on a rack.

In general, a container for storing such a sample includes a main body forming a space for accommodating the sample therein, and an opening to access the receiving space of the main body by screwing or press-fitting. It consists of a cap.

However, in recent years, there has been an increasing demand to keep the tube in a frozen or refrigerated state rather than a normal temperature environment, and an increasing demand for maintaining a sealed state to prevent leakage of the sample accommodated inside the main body. There is a greater demand for a screw-type cap than for a cap that opens and closes.

For the tube (or sample storage container) with such a screw-type cap (or lid), the operator's opening and closing operation may cause contamination to the sample during the opening and closing process. Individual opening and closing operations have a problem in that unnecessary time and labor are consumed.

Accordingly, there is an increasing demand for necessary technologies to solve these problems.

Here, the shape or number of the cap protrusions 12 protruding from the inner circumferential surface of the lid concave groove 11 is not particularly limited, but the key 150 is formed in the cap protrusion 13 formed between the adjacent cap protrusions 12. ) is preferably formed so that the corner of the column can be caught.

As a result, the key 150 is fitted into the inner circumferential surface of the lid groove 11 in which a plurality of lid protrusions 12 protrude from the inner circumferential surface, so that at least one lid protrusion 12 is rotated as the key 150 rotates. The lid 1 is rotated as an action point, and the sample storage container can be opened and closed by rotating the lid 1 in the locking or unlocking direction of the sample storage container according to the rotation direction of the key 150.

At this time, it is preferable that the lower end portion of the key 150 according to an embodiment of the present invention is formed so that the cross section of the polygonal pillar gradually widens as it goes upward.

For example, as shown in FIG. 5 , when the lower end portion of the key 150 has a square pillar shape, each corner of the bottom surface of the square pillar may have an inclined surface 1753 that is inclined outwardly toward the upper side.

Since the inclined surface 1753 is provided at the lower end of the key 150, when the key 150 is inserted into the lid groove 11, it is more tightly fitted as the key 150 is inserted into the lid groove 11, thereby preventing the key 150 and Coupling force between the lids 1 may be higher.

Meanwhile, the opening and closing device according to an embodiment of the present invention may include an ejector 160 for separating the key 150 from the lid 1.

The ejector 160 has a substantially plate shape, and a plurality of through-holes 161 may be perforated along the longitudinal direction, and a substantially rod-shaped key 150 is inserted into each of the plurality of through-holes 161. It can be inserted so that it can be raised and lowered in the vertical direction.

Here, it is preferable that the inner diameter of the through hole 161 is larger than the outer diameter of the key 150 and smaller than the outer diameter of the lid 1. That is, it is preferable that the through hole 161 is perforated so that the key 150 can pass through the through hole 161, but the lid 1 cannot pass through the through hole 161.

Also, the operation of the ejector 160 may be interlocked with the operation of the handle 130 .

That is, when the handle 130 provided to be located in the concave groove of the housing 110 that can be gripped by the user's hand is pressed inward from one side of the housing 110 by the grip force of the user's hand, the ejector 160 can correspondingly move in a downward direction.

However, only one handle 130 may be provided in the housing 110, but the present invention is not limited thereto, and one handle 130 may be provided on each of the front and rear sides, that is, a pair of handles. The user simultaneously grasps the front and rear handles, so that the ejector 160 can move in a corresponding downward direction.

8 is a diagram for explaining a method of operating an ejector according to an embodiment of the present invention.

As shown in FIG. 8, the lower end of the handle 130 and the upper end of the ejector body 135 may contact each other to face each other, and at least one key 150 disposed downward at the lower end of the ejector body 135. ) may be provided with an ejector 160 having at least one through hole 161 inserted therein.

The upper end of the ejector body 135 may have a second inclined portion 1351 inclined downward toward the front, and similarly, the second inclined portion 1351 may come into contact with the first inclined portion 1302 .

Accordingly, when the handle 130 is pulled into the housing 110 in the pressing direction, the upper end portion of the ejector body 135 can move along the first inclined portion 1302 in contact therewith, and eventually the ejector body 135 can move downwards.

When the handle 130 is moved in the pushing direction by an external force while the key 150 is inserted into the lid groove 11 of the lid 1, the ejector body 135 and the ejector 160 coupled to its lower side move downward. By moving and pushing the lid 1, the key 150 can be separated from the lid 1 of the container.

On the other hand, the handle 130 may have at least one elastic means 1301 at the rear, where the other end of the elastic means 1301 may be fixed to come into contact with the inner wall of the housing 110 (FIG. 2 reference).

When the handle 130 is pulled into the housing 110 in the pressing direction by an external force and the ejector 160 moves downward and the external force is removed from the handle 130, the elastic restoring force of the elastic means 1301 The handle 130 can return to a forward position.

Accordingly, in conjunction with the handle 130, the ejector 160 coupled to the lower side of the ejector body 135 moves upward and returns, on one side or both sides of the ejector body 135, there is an elastic means coupling protrusion 1352 ) may be provided, and the elastic means 1353 may be fitted and coupled to the elastic means coupling protrusion 1352.

It can be fixed supported. That is, when the external force pressing the ejector 160 is removed by being fixedly supported by the lower end portion of the timing belt box 171 (or the operating part 170) that does not move up and down, the elastic restoring force of the elastic means 1353 As a result, the ejector body 135 can move upward by following the rotating handle 130 .

An unexplained reference numeral p in FIG. 8 is an accommodation space in which the key 150 can be accommodated inside the ejector body 135, and the ejector body 135 responds to external force and elastic restoring force regardless of the operation of the key 150. can be moved up and down by

On the other hand, the opening and closing device according to an embodiment of the present invention may include one or more keys 150, and when a plurality of keys 150 are included, the number of keys 150 is not particularly limited, but one For example, it may be 8.

At this time, it is preferable that the plurality of keys 150 interlock with each other when rotating in the locking direction or the unlocking direction.

3 is a view showing a state in which a plurality of keys are arranged and coupled to each other according to an embodiment of the present invention.

As shown in FIG. 3, according to one embodiment of the present invention, a plurality of keys 150 are inserted and fixed to the key holder 172, and at this time, the plurality of keys 150 inserted into the key holder 172 are independently It is preferable to be coupled so as to be able to rotate.

A belt pulley 173 may be coupled to the upper end portion of each key 150 so as to interlock with each other, and the outer circumferential surface of the plurality of belt pulleys 173 is engaged with one timing belt (not shown). By doing so, the plurality of belt pulleys 173 can rotate in conjunction with each other via one timing belt.

According to an embodiment of the present invention, when any one key 150 rotates in the locking direction or the unlocking direction with the driving force generated by the driving device 180, the remaining keys 150 interlock through the timing belt By rotating by the same amount in the same direction, the opening and closing device according to an embodiment of the present invention can simultaneously open or close the lids 1 of several sample storage containers with one operation.

However, when opening or closing the lids (1) of several sample storage containers at the same time, since all the lids (1) are not locked or opened by rotating at the same rotational speed, when the lids (1) of several containers are closed at the same time , Even if the lids (1) of some containers are completely locked, it is good to continue the locking operation for the lids of the remaining containers.

Accordingly, when the key 150 according to an embodiment of the present invention rotates in the locking direction around the axis by the driving force of the driving device 180, when a resistance of a certain value or more is generated, the lid 1 is moved in the locking direction. For this purpose, the key 150 according to an embodiment of the present invention is a key coupling portion 175 fitted to the lid 1 and the driving force of the driving device 180 to the key coupling portion. It may include a shaft 174 coupled to the key coupling portion 175 to deliver to (175).

At this time, the shaft 174 and the key coupling part 175 each have rod-shaped bodies 1741 and 1751, and a key protrusion 1742 is protruded from one end of the body 1741 of the shaft 174. And, one end of the body 1751 of the key coupling portion 175 may include a coupling portion 1755 in which a key groove 1756 is formed.

Here, the lower end of the elastic means 176 may be supported on the upper surface of the key holder 172, and the upper end of the elastic means 176 may be supported on the lower surface of the belt pulley 173.

Accordingly, the key 150 does not escape to the outside of the lower part of the opening and closing device through the through hole 161 of the ejector 160 by the elastic restoring force of the elastic means 176, and the belt pulley 173 moves the timing belt box ( 171) to maintain its position.

Meanwhile, FIGS. 5 and 6 are views showing each part of a key according to an embodiment of the present invention, and FIG. 7 is a view showing a coupling part between a key coupling part and a shaft according to an embodiment of the present invention.

As shown in FIGS. 5 to 7, the coupling between the upper end of the key coupling part 175 and the lower end of the shaft 174 has a gear coupling structure, and when the key 150 rotates in the loosening direction, a constant value Even if more than a resistance force is generated, it can be implemented so that it does not spin, and when the key 150 rotates in the locking direction, it does not spin if a resistance force of a certain value or more is generated.

Specifically, as shown in the drawing, the key coupling part 175 may have a key yo groove 1756 concavely formed in the upper coupling part 175, and the key yo groove 1756 protrudes along the inner circumferential surface. It has a ratchet protrusion 1757, but the plurality of ratchet protrusions 1757 may protrude so that the distal end faces any one circumferential direction (for example, a locking direction). As a result, an intaglio gearwheel may be formed on the upper part of the key coupling part 175 .

In addition, the shaft 174 may have a key protrusion 1742 protruding from the bottom so as to be fitted corresponding to the key protrusion 1756, and along the outer circumference of the key protrusion 1742 in the opposite direction to the circumferential direction ( For example, a plurality of pole rods 1743 extending in the unwinding direction) may be included.

As a result, when the key protrusion 1742 is inserted and coupled to engage with the key-yo groove 1756, the distal end (f) of the pole rod 1743 is concavely formed between the two adjacent ratchet protrusions 1757. 1758), when the shaft 174 rotates in the disengagement direction, the distal end (f) of the pole rod 1743 is caught in the locking groove 1758, so that the key coupling part 175 does not rotate. .

At the same time, when the key protrusion 1742 having a polygonal pillar shape (for example, a triangular pillar shape) is inserted and coupled to engage the key protrusion 1756, the pillar edge of the key protrusion 1742 and the pole rod 1743 from this The extension part (b) extending to is caught on the ratchet protrusion 1757, so that when the shaft 174 rotates in the locking direction, the pillar edge of the key protrusion 1742 and/or the extension part of the pole rod 1743 (b) may press the ratchet protrusion 1757 to rotate the key coupling part 175 in the locking direction.

At this time, more preferably, the outer surface (c) of the extension (b) extending from the pillar edge of the key protrusion 1742 to the pole rod 1743 may have a curved surface, and the protrusion of the ratchet protrusion 1757 facing it As described above, the first protruding surface (a1) is formed to be inclined toward the locking direction, so that a force equal to or greater than the resisting force set by the curvature of the curved surface (c) and the inclined angle of the protruding surface (a1) When acting between the curved surface (c) and the protruding surface (a1), the key protrusion 1742 inserted into the key groove 1756 can be idle.

Eventually, when the lid 1 is completely locked by rotating the sample storage container a predetermined number of times in the locking direction, even if the key protrusion 1742 inserted into the key groove 1756 rotates with a force greater than the resistance set above, the key protrusion 1742 turns around, and the lid (1) is no longer locked to the sample storage container. Accordingly, the opening and closing device according to an embodiment of the present invention includes a plurality of keys 150, and when the plurality of keys 150 simultaneously closes the lids 1 of several containers, a portion of the lid 1 is completely locked. For the container, the key protrusion 1742 inserted into the key yo groove 1756 does not lock the lid 1 further, and the locking operation can be continued for the lid 1 of the remaining containers.

On the other hand, non-explained reference numeral a2 is a second protruding surface formed on the opposite side of the protruding first protruding surface a1 of the ratchet protrusion 1757, and the second protruding surface a2 is preferably a concave curved surface do.

This is because the distal end f of the pole rod 1743 can be easily caught in the locking groove 1758 when the key protrusion 1742 rotates in the unwinding direction by the concave second protruding surface a2.
